You are blip, the rogue byte in a computer system, and your aim is to make it through all 25 levels of security clearance to escape the evil mainframe

Use the arrow keys to move

Each level is guarded by a set of watcher programs, which will stop you in your tracks and examine you to make sure that no rogue bytes can escape. Fortunately, you can pretend to be a valid byte, but this costs you time, and you must remain still

As you go though levels you manage to improve your reflexes, and can travel quicker on your way to the safety of the blue DMZ
